This is London. Our engineer's are used to the challenge of parking in town. If you live on an estate or an area with limited pay by phone parking then yes, we will need a visitors permit to park. We will where possible use phone parking and shared use bays at no charge to yourself, however these need to be available at the time we arrive and of course be within close proximity to your property (Our engineers tool bags can weigh in at 20kg which means we need the space to be reasonably close) so it's best to have a permit available. If you have no suitable parking or permit, we reserve the right to reschedule the appointment or apply penalty charge notices to your final invoice. Please be aware that we have some big vans on our fleet, if you are planning on getting us access to park in an underground carpak, please ensure that the height limit is no less than 2.3m or let our office know in advance.
